MIXING DEV ICE FOR CARBONATIN'G APPARATUS,

Application filed August 13, 1924. Serial No. 731,784.

To all whom it may concern:

Be it known that I, ELI EDWARD SAGER, a citizen of the United States, at present residing at Seattle, in the county of King and State of Vashington, have invented certain new and useful Improvements in Mixing Devices for Oarbonating Apparatus, of which the following is a specification.

My invention relates to certain new and useful improvements in carbonating dispensers especially designed for the dispensing of carbonated water, filling of siphon bottles and filling of ordinary bottles and containers.

My invention is an improvement of that disclosed in my Patent No. 1,498,812, dated June 24, 1924, and it especially has for its object to provide certain new and useful improvements in the mixing device used in apparatus of the character stated.

In its general nature the invention resides in those novel features of construction, combination and arrangement of parts which will be first fully described, then be spe cifically pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of my invention showing the same in use for filling a siphon bottle.

Figure 2 is a horizontal section taken approximately on the line 22 of Figure 3.

Figure 3 is a vertical section with parts in elevation and parts being broken away showing how an ordinary bottle may be filled by the use of my invention.

Figure 4 is a vertical section taken approximately on the line 4-4 of Figure 3.

Figure 5 is a section taken approximately on the line 55 of Figure 2.

Figure 6 is a detail horizontal section of the control valve taken approximately on the line 66 of Figure 7.

Figure 7 is a vertical section of the control valve.

Figure 8 is a detail section of the back check valve in the water supplying duct.

In the accompanying drawings in which like numerals and letters of reference indicate like parts in all the figures, 1 indicates a cylindrical container provided with a base 2 from which extends a flange 3 forming a stand for the dispenser. The base 2 is provided with an annular groove 4 in which is fitted a rubber gasket 5. 6 designates a cylindrical bell, the lower edge of which fits into the groove 4 upon the gasket 5. The bell is located concentrically within the container 1 thereby forming a surrounding annular ice chamber 7.

8 is a groove which is'formed in the head 7 of the bell 6 and 9 is an orifice extending through the head 7 centrally thereof and from the base of the groove 8.

10 is the cover for the container casing 1. 11 designates a water supply pipe and 12 is a check valve casing provided with a suitable valve seat 13. The water supply connection 11 enters the casing 12 below the seat 13. 14 is a spider secured in the casing above the valve seat and 15 is a guide rod secured centrally in the casing 12 by the spider 14 and the bottom of such casing. 16 is a valve freely held on the rod and held upon its seat 13 by superimposed pressure.

17 is a duct leading from the upper end of the casing 12. 18 is a pipe communicating at its lower end with the duct 17 and extending yertically into the ice chamber 7. 19 1s a pipe 0011 located in the ice chamber 7, one end of which, indicated at 19*, ex-' tends upward and is connected to theupper end of the pipe 18. The opposite or lower end of the coil 19 extends through the wall of the bell 6 as indicated at 19 so as to feed the water into the lower end of the bell.

20 IS a gas supply pipe leading at one end to a duct 21 extending through the base 2 of the casing 1 so as to enter the casing withbell with water. 24 is a duct leading down-' wardly from the lower end of the pipe 23 and having a horizontal extension 24 for a purpose presently understood.

25 is a perforated pipe leading through the bottom of the casing 1 and extending upwardly into the ice chamber 26 is a valve casing and 27 is a valve located Within the casing and turnable along a vertical axis, the valve being operated by the handle .26 secured to the valve spindle 26 29 is a central duct leading up into the 11 valve 27 and provided with a horizontal extension 30. The gas supply pipe 20 at its outer end with the casing 26 so that the horizontal extension may be brought into registering position therewith;

31 is a passage formed in the valve 27 to effect communication at times between the ducts 32 and 24 32 is a duct or pipe which connects the lower end of the pipe 25 with the valve casing 26 at a point at right angles to the point of connection of the duct 24.

33 is the mixing tube, the upper end of which is connected by a union 34 to a pipe 34 (it may be integrally formed with the head 7 by casting them together), the pipe 34* fitting into the groove 8 of the head 7 of the bell 6. The tube 33 depends into proximity with the bottom of the hell 6 as clearly indicated in Figures 3 and l.

are a series of perforated disks driven into the tube and spaced apart by the spacers 36 that are mounted on a central rod 37.

38 is a siphon filling device and 39 a single dispensing nozzle that may, however, be fitted with suitable attachments adapting it for the filling of ordinary bottles or flasks, see dotted lines in Figure 3, and as will be more fully explained later. The nozzle 39 is controlled by a conventional valve mechanism 40 such as is commonly used on soda fountains and is provided with the usual means for effecting either a needle spray or an ordinary filling stream.

The siphon filler 38 has a seat 38 provided with a washer 38 against which the nozzle N of the siphon bottle S may rest to effect communication between it and the duct 38 which is controlled by the valve 41.

38" is a lever pivoted at 38 and having a presser 38 for pressing down the valve mechanism 8 of the siphon bottle S so as to open communication with the interior of the bottle. When the valve 21 is opened the carbonated water is forced into the siphon bottle, it being of course assumed that the lever 38 is pressing downat the same time.

In order to brace or support the siphon bottle S a suitable support 38 is provided, it having a rest 38 at its-bottom against which the siphon bottle is held.

42 is a gauge glass to indicate the fluid level within the hell 6 and 4-2 is a gauge to indicate the pressure within the bell.

The pipe 34F communicates with each of the filler mechanisms 38 and 39 respectively as indicated in Figure 3 of the drawings.

So far as described the operation of my apparatus will be understood as follows: Assume the vessel to be empty and it is desired to fill the same with water and charge the water; assume-further that a source of carbonic acid gas under pressure is suitably coupled to the connection 29} of the valve mechanism 26 and assume that a source of water supply under ordinary pressure to be connected to 11. hen the valve 27 is turned sothat the passages 31 effect communication between the ducts 24 and 32 (the valves 40 and 41 being of course closed) the interior of the bell 6 is brought into communication with the atmosphere through the pipe 25 with the result that the water pressure in the duct 11 opens the chamber 16 and the water flows into the bell 6 until it has reached the desired height, whereupon the attendant moves the valve 27 to close the passage 31 from communication with the ducts 24F and 32, thereby sealing the bell 6 from the atmosphere. By turning the valve 27 until the passage 30 comes into communication with the duct 20 the pressure from the gas reservoir will cause the gas under that pressure to flow through the pipe 20, duct 21, to the perforated pipe 22, from which it is liberated through the fine openings therein into the water contained within the bell 6, thereby charging the water. As soon as the gauge 42* indicates the desired pressure the operator may close the gas supply by moving the valve 27 sufficiently to close the duct 30 to leave communication with the duct 20.

If desired the connection with the gas supply may be left on. The pressure with in the bell 6 due to the charging gas, as soon as it exceeds the water pressure in the duct 11, causes the valve 16 to close and prevents the further admission of water.

Pressure now being fully established within the bell 6, the opening of either of the valves 40 or 41 will cause the carbonated water to flow upwardly in the tube 33 through the several perforated disks of the mixing tube, thus breaking the water up so as to immediately and thoroughly co-mingle with the gas, the water flowing through the pipe 34 to the valves 40 and 41 so that when those valves are opened the charged water may either be dispensed into a glass, as indicated in dotted lines at the right of Figure 1, or made to fill a siphon bottle as indicated in full lines at the left in Figure 1, or both operations may be conducted at the same time if desired.

When it is desired to fill an ordinary bottle the short nozzle 39 is unscrewed and a long nozzle 39" is substituted which will reach down into the bottle and permit the filling of the same as indicated in dotted lines in Figure 3.

Attention is also directed to the fact that while I have shown but one ordinary dispensing nozzle for ordinary dispensing purposes and bottle filling purposes, it is quite obvious that these may be duplicated without departing from the invention and as such duplication would be a mere mechanical variation description thereof is thought to be unnecessary.

Any suitable safety valve V may be employed to relieve excessive pressure within the bell 6. As the control of such valve per se forms no part of my present invention detailed illustration thereof is thought to within the same adjacent the bottom there-- of, a series of perforated disks fitting the tube and located within the same, spacers between adjacent disks and a rod on which said disks and spacers are located, and

means to hold said rod in place, all being arranged whereby the contents of said reservoir will be caused to pass upwardly through said tube and the. perforated disks from the bottom of said reservoir to the place of discharge thereby mixing the gas and liquid.

2. In carbonating and dispensing apparatus of the type wherein is provided a reservoir with a fluid outlet in its top in which the liquid and gas are charged and from which they are dispensed; a mixing device consisting of a tube secured to the top of the reservoir and extending down within the same adjacent the bottom thereof, a series of perforated disks fitting the tube and located within the same, spacers between adjacent disks and a rod on which said disks and spacers are located, means to hold said rod in place, said means comprising a perforated body held in the bottom end of said tube and into which said rod is secured, all being arranged whereby the contents of said reservoir will be caused to pass upwardly through said tube and the perforated disks from the bottom of said reservoir to the place of discharge thereby mixing the gas and liquid.

ELI EDWARD SAGER.
